An information system for developing information systems

This paper considers a paradigm for the development of software through the use of a complete, integrated-design database. A prototype information system for the implementation of information management systems is then described. This tool manages the requirement definitions, the process and data flow, and all design and operational documentation. Using a relational-data model and program specifications, it generates programs in a selected target language. The results of two years' production use are presented, and the potential for transfer of the concept is examined.
